Tim Steiner of Ocado

. The online grocer’s shares briefly touched 285p in February. They’re now 57p after a profits warning this month. Steiner’s trust sold 2m shares in February at 254p, banking £5.1m, but still owns 27.7m shares. At the top, that holding was worth £79m; now it’s valued at £16m.

Julian Dunkerton of SuperGroup

. In stock market terms, the retailer of pseudo Japanese T-shirts and other kit has gone out of fashion. The share price has fallen from £13 in January to 531p. The founder’s 32% holding is still worth £138m - nice, but not as nice as the £340m at last new year, or the £475m when the shares peaked at £18.20 in February.

Glencore CEO Ivan Glasenberg

. The chief executive of the giant commodities trader saw his stake of almost 16% valued at just under £6bn at flotation in May. The listing was priced at 530p. Price today: 396p. Glasenberg has picked up a $54m dividend along the way, which he used to buy more Glencore shares, but the 25% price plunge represents a loss of about £1.4bn in the value of his holding.

John Paulson of Paulson and Co

. The hedge fund manager emerged from obscurity in 2007 with a spectacular winning bet against US sub-prime mortgages. Betting on a US recovery has been a losing bet this year. The flagship Advantage Plus fund was down 46% in the first eleven months of the year; the Advantage fund, which doesn’t borrow to exaggerate returns, lost a third of its value. Paulson, with most of his billions invested in his own funds, will be feeling the pain

Jon Corzine

. The former chairman of Goldman Sachs and former governor of New Jersey staked his reputation on turning broker MF Global into a Wall Street powerhouse. Instead, in October MF became the eighth largest US bankruptcy, with as $1.2bn in customers’ funds going missing. “I simply don’t know where the money is,” Corzine told a congressional inquiry. He waived $12m in compensation as he departed; the loss of credibility is greater.

UK public

. We own 83% of Royal Bank of Scotland and 41% of Lloyds Banking Group. Both shares have been dogs this year: RBS down 48% and Lloyds 60%. In total, we’ve sitting on a loss of about £35bn on stakes originally worth £60bn. It almost makes the loss of £400m-ish on this year’s sale of the “good” part of Northern Rock seem a rounding error.

GLG hedgies

. Man Group snapped up the GLG hedge fund last year for $1.6bn in an attempt to reinvigorate its business. Fund management is a people business so GLG’s superstar partners - Noam Gottesman, Pierre Lagrange and Manny Roman (pictured) - had a three-year lock on the Man shares they received. Those shares have more than halved in value this year. Roughly speaking, the combined paper loss for the trio is £250m.
